Wireless 4.0 Ah Battery

November 2015

With the release of the WCBAT620 18V 4.0 Ah wireless battery, Bosch delivers even greater runtime from the company’s Power Ready Wireless Charging System. The WCBAT620 18V battery offers 50% more runtime versus the current 2.0 Ah wireless battery. Both the 4.0 Ah and 2.0 Ah Bosch wireless batteries offer up to 100% longer life versus conventional batteries thanks to Bosch-exclusive CoolPack technology.
This 4.0 Ah Wireless battery is based on the Bosch Power Ready Wireless Charging System. The wireless charging system gives professional users the ability to charge their tool when not in use without having to disconnect the battery from the tool. This saves both time and money because less charging time is required, and with the 4.0 Ah battery, no extra batteries are required to complete a day’s jobs.
The Bosch WCBAT620 4.0Ah Wireless Battery starts with the same heritage shared by all Bosch batteries: CoolPack technology, which delivers up to 100 percent more recharge life versus other battery packs thanks to heat-conductive housing that keeps the battery cool. The battery will perform in cold weather conditions down to –4ºF.
Combined with heat reduction is single-cell monitoring, a technology that maximizes cell usage and life. Each Bosch wireless battery also includes an LED indicator that shows state of charge. In addition, all Bosch wireless batteries are part of a flexible power system that ensures 100% compatibility with all of the company’s 18V Lithium-ion power tools.
Charging times for a completely depleted Bosch WCBAT620 4.0 Ah Wireless Battery are 80% in 65 minutes, 100 percent in 85 minutes.
